Phase continuity associated with reconfigurable intelligent surfaces

An apparatus for wireless communications at a first wireless device, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, wherein the instructions are executable by the processor to:
• obtain, from a reflective surface, capability information indicating a capability of the reflective surface to maintain phase continuity across a plurality of transmissions according to a first set of transmission parameters;
• output, based at least in part on the capability information, control signaling indicating one or more conditions under which the reflective surface is to maintain phase continuity;
• and
• output wireless signaling to at least a second wireless device via the reflective surface according to a phase continuity condition based at least in part on the one or more conditions.

A method for wireless communications at a reflective surface, comprising:

• transmitting capability information indicating a capability to maintain phase continuity across a plurality of transmissions according to a first set of transmission parameters;
• receiving, based at least in part on the capability information, control signaling indicating one or more conditions under which the reflective surface is to maintain phase continuity;
• and
• relaying wireless signaling between at least a first wireless device and a second wireless device according to a phase continuity condition based at least in part on the one or more conditions.
